The initiative will be discussed at the first “green summit” between Simon Burns, the rail minister, officials and conservation groups in Whitehall over the £33.1 billion 351-mile scheme.

While the Government has described HS2 as the “greenest high speed railway in the world”, critics have said it will devastate the countryside in its wake.

Particular concern has been raised over the impact of massive viaducts along the route, such as at Church Fenton is a historic North Yorkshire farming village, which lies on the spur linking the line to the existing rail network.

A number of key groups, such as the Campaign to Protect Rural England, who have been vociferous opponents of the project, have been invited to the summit.

One key concession would see groups working with the Design Panel of architects and engineers to see how the environmental impact of some of the biggest structures could be reduced.
